  18650 lithium-ion battery pack process quality characteristics

  1. Use lithium-ion batteries that pass the quality standard. Qualified and stable suppliers must supply single batteries with good performance. The single batteries have passed a series of safety tests and performance tests, and are used after passing the test.

  2. The internal resistance of the battery is required to be low and the consistency is good. Regardless of the 14.8V lithium-ion battery pack or other energy storage battery packs, low internal resistance must be ensured to ensure the capacity, platform, and heat dissipation of high-current discharge.

  3. The battery structure adopts ventilation design, and the distance between two adjacent batteries is not less than 2mm. This structure requires plastic brackets to fix the batteries.

  4. The PACK battery factory uses slotted nickel sheets for spot welding. The size of the nickel sheets meets the requirements of high-current discharge. The material of the nickel sheets ensures low internal resistance. The spot welding machine ensures stable work, the quality of the welding needles is guaranteed, and the operators are trained and qualified. After the on-the-job operation, check whether the solder joints are firm after spot welding. In addition, each batch of products is subjected to a vibration test to verify the anti-vibration performance.

  5. Different batches of batteries are made into typical finished products and life tests are performed. When the relevant experience of lithium-ion battery PACK design specifications is summarized, the battery finished products are subjected to cycle tests to obtain the actual cycle life.

  6. Verify the high and low temperature performance of the battery. The cells of different PACK lithium-ion battery manufacturers are made into finished products and are subjected to different rate discharge tests at high and low temperatures to obtain actual discharge curves.
